Question

explain three points of difference between straight muscles and smooth muscles​

Answer 1

Skeletal Muscles:-

• Are directly attached to the skeleton by tendons.

• Aid in movement and locomotion.

• Are voluntarily activated.

• Appear striped under a microscope. Also called "striated" muscle.

• Fatigue more quickly than smooth or cardiac muscles.

• Are able to stretch and resume original shape.

Smooth Muscles:

• Get their name from their smooth appearance under a microscope.

• Arranged in bundles of muscle fibre sheets.

• Contract involuntarily. Regulated by autonomic part of nervous system.

• Found in walls of hollow structures, including veins, arteries, and intestines.

• Maintain flow of fluid and food along hollow structures.

• Found in hair erectors, pupils, gland ducts, esophagus, bronchi, intestines, stomach, and blood vessels.

$<b><u>$➡Smooth muscles are
involuntary muscles; the individual has no control over their contraction and relaxation. Skeletal muscles, however, are voluntary muscles; one has complete control over their contraction and relaxation. Smooth muscles are non-striated like cardiac muscles, while skeletal muscles are striated.
